Troubleshooting & Fix Common Errors

If you encounter unexpected errors or installation failures, apply these verified diagnostic fixes:

❌CUDA Out of Memory (OOM) Error

Root Cause: Your GPU VRAM is full because the AI model batch size or resolution is too high.

💡 Solution Fix: Add '--lowvram' or '--medvram' argument to your launch command script, or lower the image/video batch size to 1.

❌'git', 'python' or 'ffmpeg' is not recognized as an internal command

Root Cause: The required software is installed but not added to your Windows Environment System PATH.

💡 Solution Fix: Reinstall Python / Git and make sure to check the box 'Add Python.exe to PATH' during installation.

❌Torch / PyTorch CUDA Version Mismatch

Root Cause: Installed PyTorch binary does not match your Nvidia GPU CUDA driver version.

💡 Solution Fix: Run: pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118

❌Port 7860 or 8888 Already in Use

Root Cause: Another WebUI or Python background process is already running on the default local port.

💡 Solution Fix: Close existing terminal windows, or add '--port 7861' parameter to change the default listening port.
